Bug Description

on unity 11.04,11.10 seraching for "game", "internet" or such generic keywords in the lenses does not show all relevant applications..
this is a showstopper bug for me and other people i talked to
i understand the difficulty of insuffiecient metadata for applications but escpecially for newbys and "non-geek"s this is at least a big MUST.
You DO have descriptions and categories in software center.. can't these info be used in the lens too?

Desired solution:
Stick to the X-GNOME-Keywords field in the .desktop files, but improve the indexed data.
- Minimally: Assure that key apps have good keywords in their packages
- Best: Get the word out to have upstreams put good data in there. Help upstreams getting this done.

Also:
12:51:48 <Trevinho> what about not only considering the Keywords .desktop file field (that is alredy supported, for applications that specify it) but also the category of each application?
12:52:23 <Trevinho> I mean, if I search for "internet" or "games", I expect that all the programs under that category are shown into the dash, isn't it?
12:53:39 <Trevinho> Of course, programs that have full matching (ie. name contains that string) would get the priority, but if I search for "System" I expect that all the applications under "System" category are shown, not only System Monitor for example...
13:21:02 <JohnLea> yes considering the category of the application would be an improvement

I am not overly keen on using the description from the software center. As it stands many of the descriptions there are of poor quality to "normal" users. They seem to be written to other packagers. This can change of course. (and are those descriptions translated?)

A simpler solution would be to just use X-GNOME-Keywords which we do support in unity-lens-applications (as I also mentioned in bug 833610).

I am commenting here because it seems related. Doing a partial search yields better results than a more specific one. For example, I wanted to open Brasero Disc Burner from the dash so I typed "cd burner" and while Brasero did show when I typed cd, it dissappeared when I typed burner (which is funny because that word happens to be part of the name of the application).
